How much heat in joules is needed to raise the temperature of 1.0 L of water from 0 C to 100 C?
100*1*4,186.8= 418,680
Time required to raise 1 degree centigrade in 1 liter of water?
To determine the time this will take, you need to know the rate at which heat is being added to the system. The specific heat capacity of a substance is the amount of energy required to raise the temperature of one gram of a substance one degree centigrade. For water at 25oC, the specific heat capacity is 4.184 J*g-1*oC-1. That is, if you have one gram of water, you must add 4.184 Joules of energy (heat) to raise the temperature one one degree centigrade. The time it takes for the temperature increase to happen depends on how quickly you add the 4.184 J. Adding heat at a rate of 1 Joule/second (which is equivalent to 1 Watt), it is easy to see that it will take 4.814 seconds to raise the temperature of the gram of water one degree centigrade. The first step to solving your problem, then, is to make your data units compatible with your known constants. We need to convert volume to mass. We do this by means of density. The density of liquid water at standard temperature and pressure is 1g/mL. 1L H2O *1000mL/1L *1g H2O/mL H2O= 1000g H2O Then, to find the amount of energy required to change the temperature of the mass, we use the specific heat. 1000g H2O *4.184J/(g*K)= 4184 J/oC Note the units on this last value. They give the amount of energy needed required per degree centigrade of change in the temperature. That is, it requires 4814J to change the temperature of 1000g H2O one degree centigrade. Given the time rate of heat transfer into the system, you can find the time required to make the change. If, for instance, your heat exchange rate is 5 Watts (J/s), you would have 4184 J/oC * 1 second/5 Joules = 836.8 s/oC This value allows you to calculate the time required for any change in temperature simply by multiplying the number of degrees centigrade temperature change. For one degree, we find 836.8 s/oC *1oC = 836.8s
If the kcal is 185 what is it in calories?
184,999.99989344 in 185 kcals 1 joule = 0.239005736 calories 1 kilocalorie (kcal) = 4184 joules 185kl x 4184 Joules x 0.239005736 calories = 184,999.99989344
What is the unit if he energy used in physical science and feed science?
A Joule is the SI unit of energy. It is equal to 1 Newton force, multiplied by 1 meter.The calorie is a heat energy unit. Equal to approx 4.184 Joules. In food Calories, is actually equivalent to a kilocalorie (1000 calories, or 4184 Joules).
4 calories contains how many watts?
16,736 since 1calorie= 4184 joules.
What is used to measure enegry?
Energy is measured in Joules or calories. One calorie is equal to 4.184 Joules, not to be confused with kilocalories or Calories (with a capital C) which, in concordance with the metric system is equal to 4184 Joules.
What is a person's maximum number of METS called?
A person's maximum number of METS is also called kcal level. Kcal is also known as kilocalorie. 1 Kilocalorie is equal to 4184 joules.
How many calories required to raise temperature of 1 liter of water 1 degree centigrade?
Well, let's see. Water at room temperature has a heat capacity of 4.18 J/g-C, and water also has a density of 1g/mL. If there's one litre of water, there's 1000 g of water. If the change in temperature is 1 C, and there are 1000 g of water, and specific heat capacity's 4.18... Q = mcT Q = (1000g)(4.18J/g-C)(1 C) Q = 4180 J So you need 4180 J of heat. *************************************** The definition of one calorie is as stated in the question. One calorie is equivalent to 4.18 Joules. Not sure where the maths went wrong but just so you know.
What is a kilocalery?
A kilocalorie is one food calorie. A standard calorie is a unit of energy equal to 4.184 joules. This is a very small amount of energy, so when we're talking about the amount of energy in food, we use kilocalories, which is equal to 1000 standard calories. When we're talking about food, we always say that it has so many calories, but forget to note that we're talking about food calories, which makes it somewhat confusing. 1 standard calorie= 4.184 joules 1000 standard calories= 1 kilocalorie= 1 food calorie= 4184 joules If a piece of food has 80 (food) calories, then it has 80 kilocalories, or 80,000 standard calories.
